In preparation for moving NOTES into RO_DATA, remove the PT_NOTE
workaround since the kernel requires at least gcc 4.6 now.

Thanks!

For the archives, Joel tried a similar patch a while back which caused
some problems, see:

  https://lore.kernel.org/linuxppc-dev/20190321003253.22100-1-joel@jms.id.au/ (local)

and a v2:

  https://lore.kernel.org/linuxppc-dev/20190329064453.12761-1-joel@jms.id.au/ (local)

This is similar to his v2. The only outstanding comment on his v2 was
from Segher:
  (And I do not know if there are any tools that expect the notes in a phdr,
  or even specifically the second phdr).

But this patch solves that by not changing the note.

Ah yes. Agreed: I'm retaining the note and dropping the workarounds.
FWIW, this builds happily for me in my tests.
